In the human excretory system, liquid waste is filtered from the bloodstream and eliminated from the body. What is the correct sequence of organs through which urine travels from its production to excretion?

  1. 1Kidneys
  2. 2Ureters
  3. 3Urinary bladder
  4. 4Urethra

Cevap

The correct sequence from production to excretion is Kidneys, Ureters, Urinary bladder, and Urethra.
Urine formation begins in the functional units (nephrons) of the kidneys. Once formed, urine drains through the renal pelvis into the two ureters, which transport it downward to the urinary bladder for temporary storage. When the bladder contracts during urination, urine is discharged out of the body through the urethra.

Adım Adım Çözüm

1
Identify the site of urine formation.
Kidneys filter blood to produce urine.
Urine production begins in the microscopic nephrons of the kidneys.
2
Trace the pathway from the kidneys toward storage.
Urine travels through the ureters.
The ureter tubes directly conduct urine from the renal pelvis down to the bladder.
3
Identify the temporary storage organ.
Urine enters the urinary bladder.
The bladder expands to hold urine until micturition occurs.
4
Determine the final duct for excretion.
Urine exits through the urethra.
The urethra serves as the single final passage connecting the bladder to the exterior.
